Entry Format

The Anatomy of a Good Entry

### New: Bulk Export for Reports 📊

You can now export up to 10,000 rows at once from any report view.
Select your rows, click Export, and choose CSV or Excel format.

Previously limited to 500 rows per export.

Structure: Category label -> User-facing title -> What you can do now -> How -> What changed -> Visual

User-Facing Language

❌ Internal language:
"Implemented batch processing queue for the export service"
"Refactored the ReportExporter class to support pagination"
"Fixed bug in CSV serialization (PR #4521)"

✅ User-facing language:
"You can now export up to 10,000 rows at once from any report"
"Reports now load 3x faster when filtering large datasets"
"Fixed an issue where exported CSV files had missing columns"

Rules:

• Write what the user can DO, not what you BUILT
• Start with "You can now..." / "Reports now..." / "Fixed an issue where..."
• Include the benefit, not just the mechanism
• Use present tense

Categories

Standard Categories

Category	Color	Icon	Use For
New	Green	✨ or 🆕	Entirely new features or capabilities
Improved	Blue	⚡ or 🔧	Enhancements to existing features
Fixed	Yellow/Orange	🐛 or 🔨	Bug fixes
Removed	Red	🗑️ or ⚠️	Deprecated or removed features
Security	Purple	🔒	Security patches

Categorization Rules

• New = something users couldn't do before at all
• Improved = something users could do, now it's better/faster/easier
• Fixed = something that was broken, now works correctly
• Don't use "Updated" — it's meaningless. Was it improved or fixed?

Version Numbering

MINOR	New features, backward-compatible	3.1.0 -> 3.2.0

Date-Based Versioning

Breaking Changes

Breaking changes need special treatment:

### ⚠️ Breaking: API v2 Endpoints Deprecated

**What changed:** API v1 endpoints will stop working on March 15, 2026.

**What you need to do:**
1. Update your API calls to use v2 endpoints ([migration guide →](link))
2. Update authentication to use Bearer tokens instead of API keys
3. Test your integration before March 15

**Timeline:**
- Now: v2 endpoints available, v1 still works
- March 1: v1 returns deprecation warnings
- March 15: v1 stops working

Writing Tips

Do

• Group related changes together
• Lead with the biggest/most requested change
• Link to documentation for complex features
• Include who requested it ("By popular request:")
• Show migration paths for breaking changes
• Date every entry

Don't

• Don't say "various bug fixes" — list specific fixes or skip them
• Don't include internal references (PR numbers, ticket IDs, branch names)
• Don't use "Updated [feature]" without saying how
• Don't list changes nobody cares about (dependency bumps, internal refactors)
• Don't commit-dump — one changelog entry may represent many commits

Changelog Frequency

Product Type	Frequency	Notes
SaaS (continuous deploy)	Weekly batch	Group a week of changes
SaaS (major features)	Per feature launch	With blog post
Versioned software	Per version release	Tied to semver
API	Per version + deprecation notices	Include migration guides
Mobile app	Per app store release	Match store listing "What's New"

Common Mistakes

Mistake	Problem	Fix
Developer language	Users don't understand	Write what users can do
"Bug fixes and improvements"	Zero information	List specific fixes
No dates	Can't tell what's new	Date every entry
No visuals	Users skip text	Screenshot major features
Breaking changes buried	Users discover too late	Prominent warning + timeline
Commit log as changelog	Noisy, unhelpful	Curate and rewrite
